Description

Изобретение относитс  к способам получени  гор чего дуть , ндироко примен емого во многих отрасл х промышленности, и, в частности , в металлургической промышленности дл  доменных печей.5 Известен способ высокотемпературного нагрева и сжати  дуть  дл  доменных печей, включаюш,ий сжатие и предварительный нагрев технологического дуть . Недостатком известного способа нагрева дутьевого возду- 10 ха  вл етс  то, что наибольша  устойчива  температура дуть  при нем не превышает 1200°С из-за отсутстви  жаростойких конструкционных материалов. Дл  получени  технологического дуть  с 15 более высокими параметрами (t 5QO°C) предлагаетс  способ, по которому дутье дополнительно сжимают в скачках уплотнени  в энергообменнике при отношении давлений и расходов газа и технологического дуть  со- 20 ответственно равных 1,2-2 и 1,2-2,5. Поскольку стенки энергробменника попеременно подвергаютс  действию газа высокого давлени  и низкого давлени , лричем около 80% времени цикла занимает выпуск от- 25 работавшего газа высокого давлени  и впуск газа низкого давлени , то средн   равновесна  температура стенки не превышает допустимой . Это дает возможность использовать существующие конструкционные материалы, зо Способ осуществл ют следующим образом. Дутьевой воздух, предварительно слсатый в компрессоре до давлени  2,5 ата, подогревают в каупере до температуры 1200°С, затем направл ют в энергообменнпк, в скачках уплотнени  которого происходит обмен энергий дутьевого воздуха и продуктов сгорани  (газ высокого давлени ). После энергообменника дутьевой воздух с 1510°С и Р-- 5 ата поступает в доменную печь. В роли газа высокого давлени  в энергообменнике выступают продукты горени  доменного газа или природного, частично используютс  продукты горени  за купером. После энергообменника избыточное давление продуктов сгорани  срабатываетс  в газовой турбине. Предмет изобретени  Способ высокотемпературного нагрева и сжати  дуть  дл  доменных печей, включающий сжатие и предварительный нагрев технологического дуть , отличающийс  тем, что, с целью получени  технологического дуть  с более высокими параметрами, дутье дополнительно сжимают в скачках уплотнени  в энергообменннке лри отношении давлений и расходов газа и технологического дуть  соответственно равных 1,2-2 и 1,2-2,5.The invention relates to methods for producing hot blowing, which is used in many industries in the industry, and in particular, in the metallurgical industry for blast furnaces.5 There is a known method of high temperature heating and compression blowing for blast furnaces including compression and preheating of the technological to blow. A disadvantage of the known method of heating the blast air is that the highest stable temperature of blowing with it does not exceed 1200 ° C due to the absence of heat-resistant structural materials. In order to obtain a process blow with 15 higher parameters (t 5QO ° C), a method is proposed whereby the blast is further compressed in compaction jumps in the energy exchanger at a ratio of pressures and flow rates of gas and process blow respectively 20 and 2-2 and 1, 2-2.5. Since the walls of the energy source are alternately exposed to high pressure and low pressure, it takes about 80% of the cycle time to take out the spent high pressure exhaust gas and the low pressure gas inlet, the average equilibrium wall temperature does not exceed the allowable one. This makes it possible to use existing construction materials, the method is carried out as follows. The blast air pre-squeezed in the compressor to a pressure of 2.5 ata is heated in the Cooper to a temperature of 1200 ° C, then sent to energy exchangers, in which compaction jumps the energy of the blown air and the combustion products is exchanged (high pressure gas). After the energy exchanger, the blast air from 1510 ° С and Р-- 5 atm enters the blast furnace. In the role of high-pressure gas in the energy exchanger are the products of combustion of a blast furnace gas or natural gas, and the products of combustion behind the Cooper are partially used. After the energy exchanger, the overpressure of the combustion products is triggered in the gas turbine. The subject of the invention is a method of high-temperature heating and compression blowing for blast furnaces, including compression and preheating of process blowing, characterized in that, in order to obtain a technological blow with higher parameters, the blast is further compressed in pressure jumps in the energy exchange ratio of pressures and gas flow rates and technological blow respectively 1.2-2 and 1.2-2.5.
